Cytek Biosciences Reports Second Quarter 2024 Financial Results

FREMONT, Calif., August 6, 2024 (GLOBE NEWSWIRE) — Cytek^® Biosciences, Inc. (“Cytek Biosciences” or “Cytek”) (Nasdaq: CTKB), a leading cell analysis solutions company, today reported financial results for the second quarter ended June 30, 2024.

Recent Highlights

• Total revenue for the second quarter of 2024 was $46.6 million, representing a 4% increase sequentially over the first quarter of 2024 and a 6% decrease over the second quarter of 2023

• For the first half of 2024, total revenue grew 5% compared to the first half of 2023

• Launched Enhanced Small Particle (ESP^™) detection, an upgrade option for the Cytek Aurora^™ and Northern Lights^™ systems for the analysis of viruses and other sub-cellular components

• Attained a total installed base of 2,656 Cytek instruments, including the Amnis^® and Guava^® instruments shipped since the acquisition of the flow cytometry and imaging business from Luminex Corporation in February 2023, adding 147 units in the second quarter of 2024

• Repurchased $2.7 million of Cytek stock in open market purchases during the second quarter of 2024 under a new $50 million share repurchase program, following the expiration of the previous $50 million repurchase program at the end of 2023

“In the second quarter of 2024, we posted strong year over year double-digit revenue growth in EMEA and APAC as well as in our service business worldwide as compared to the second quarter of 2023. However, this performance was offset by a decline in our U.S. instrument sales, particularly among academic and government customers,” said Dr. Wenbin Jiang, CEO of Cytek Biosciences. “Despite the headwinds in the U.S. market, we believe the fundamental drivers of long-term growth remain in place, and the underlying opportunity for our products remains strong. We remain focused on executing our business strategy and delivering durable growth and profitability and strong value to our customers and shareholders.”

Second Quarter 2024 Financial Results

Total revenue for the second quarter of 2024 was $46.6 million, a 6% decrease compared to the second quarter of 2023. The decline in revenue was related to weakness in the U.S. instrument market, offset by strong revenue growth across the EMEA and APAC regions.

Gross profit was $25.4 million for the second quarter of 2024, a 10% decrease compared to the second quarter of 2023. GAAP gross profit margin was 55% in the second quarter of 2024 compared to 57% in the second quarter of 2023. Adjusted gross profit margin, after adjusting for stock-based compensation expense and amortization of acquisition-related intangibles, was 58% in the second quarter of 2024 compared to 60% in the second quarter of 2023.

Operating expenses were $34.0 million for the second quarter of 2024, a 9% decrease from $37.3 million in the second quarter of 2023. The decrease in operating expenses was primarily driven by reduced research and development and sales and marketing expenses.

Research and development expenses were $10.0 million for the second quarter of 2024 compared to $12.1 million for the second quarter of 2023.

Sales and marketing expenses were $12.3 million for the second quarter of 2024 compared to $14.4 million for the second quarter of 2023.

General and administrative expenses were $11.7 million for the second quarter of 2024 compared to $10.8 million for the second quarter of 2023.

Loss from operations in the second quarter of 2024 was $8.5 million compared to loss from operations of $9.1 million in the second quarter of 2023. Net loss in the second quarter of 2024 was $10.4 million compared to a net loss of $4.4 million in the second quarter of 2023.

Adjusted EBITDA in the second quarter of 2024 was $2.9 million compared to $1.5 million in the second quarter of 2023, after adjusting for stock-based compensation expense, foreign currency exchange impacts and acquisition-related expenses.

Cash and marketable securities were $277.2 million as of June 30, 2024, compared to $270.4 million as of March 31, 2024. This represents an increase of $6.8 million, despite a cash expenditure of $2.7 million for the repurchase of Cytek shares during the second quarter.

2024 Outlook

Cytek Biosciences narrowed the range of its 2024 revenue guidance, now expecting full year 2024 revenue to in the range of $203 million to $210 million, representing growth of 5% to 9% over full year 2023, assuming no change in currency exchange rates. In addition, Cytek expects to report a net loss in the single digit millions for the full year 2024 due to an outlook of slightly lower gross profit, higher than expected stock-based compensation, and lower other income. Cytek expects to generate positive cash flow from operations in 2024.

Statement Regarding Use of Non-GAAP Financial Information

Cytek has presented certain financial information in accordance with U.S. GAAP and also on a non-GAAP basis for the three-month periods ended June 30, 2024 and June 30, 2023. Management believes that non-GAAP financial measures, including “Adjusted gross profit margin” and “Adjusted EBITDA” referenced above, taken in conjunction with GAAP financial measures, provide useful information for both management and investors by excluding certain non-cash and other expenses that are not indicative of the company’s core operating results. Management uses non-GAAP measures to compare the company’s performance relative to forecasts and strategic plans and to benchmark the company’s performance externally against competitors. Non-GAAP information is not prepared under a comprehensive set of accounting rules and should only be used to supplement an understanding of the company’s operating results as reported under U.S. GAAP. Cytek encourages investors to carefully consider its results under GAAP, as well as its supplemental non-GAAP information and the reconciliation between these presentations, to more fully understand its business. Reconciliations between GAAP and non-GAAP operating results are presented in the accompanying tables of this release.
